GSC Power-Division Camshafts S2 Grind
Subaru STI 2004-2007
Features & Product Details
RallySport Direct proudly carries a great selection of camshaft upgrades brought to you by GSC Power Division.
Here, you are looking at the GSC Power-Division S2 Camshafts. These have been designed to work with the USDM engines with intake-only AVCS. Additionally, these cams are ideal to suit those with high-horsepower builds with a power range of 500 WHP and above. A built head will most certainly benefit from these camshafts, but at the least, upgraded valve springs are required to employ these cams.
